How hard it is to add features to Batch Create

I am developing new multisite / network on wordpress and i found Batch Create to help me out creating multiple blogs. My problem is that I have lots of data in csv / xls file and I really need to find a way to automate adding information to created blogs.

They key idea is to create blogs which have static page as homepage and one blog page. I would like to create some information to homepage on the same time when the blog page is created for example contact information. The amount of data is so huge that its impossible to add it manually.

How hard it is to add this kind of feature to batch create?

And then there is a problem that when Im running batch create it creates 1-4 blogs at a time. And i have to start the process again many times. Any idea what can cause this? I have tried deactivating all other plugins already.
